Aligned with cytochrome b sequences from 29 siluriforms in japan, korea, russia, africa, north america and south america retrieved from genbank, and selected astyanax mexicanus, phenacogrammus interruptus, cyprinus carpio and oncorhynchus mykiss as outgroups, which are belonging to characiformes, cypriniformes and salmoniformes, respectively. we constructed a matrix of 65 dma sequences. the kimura ' s two - parameter distances were calculated and molecular phylogenetic trees were constructed by using the maximum parsimony ( mp ), maximum likelihood ( ml ) and neighbor - joining ( nj ) methods
所得序列與從genbank下載的分佈於非洲、北美洲和南美洲等地的鯰形目魚類同
一基因序列進行排序,並選用脂
鯉目( characiformes )的墨西哥麗脂
鯉( astyanaxmexicanus ) 、斷線脂
鯉( phenacogrammusinterruptus ) ,
鯉形目( cypriniformes )的
鯉( cyprinuscarpio )以及鮭形目( salmoniformes )大麻哈魚屬的oncorhynchusmykiss作外類群。
Annual expenditure totalled hk $ 10. 8 billion. through the inclusion of more environmentally friendly elements within projects such as health education and exhibition centre in kowloon park, slaughter house in sheung shui, museum of coastal defence in lei yue mun, and the award winning designs such as the belcher bay garden, the " hong kong garden " in the kunming international horticultural exposition and the swimming pool complex in taipo, we are gradually improving the environment of hong kong
本署
一向重視環境保護,建築署設計的多項工程包括九龍公園健康教育及展覽中心、上水屠房、
鯉魚門海防博物館,以及多個得獎項目如卑路乍灣公園、大埔公眾游泳池、昆明國際園藝博覽會的香港園等,都設有環保的系統或設施,為改善香港環境盡
一分力。
High concentration short - time impact examination showed that the impact of pyrethroid on carp is not severe when the case of concentration is not too high and time is not too long, most of the poisoned carp come back after the carp that exposured high concentration cycloprothrin were transferd to fresh water
高濃度短期沖擊試驗說明在擬除蟲菊酯濃度不太高,暴露時間不太長的情況下對
鯉魚的毒性影響不大,受到高濃度擬除蟲菊酯暴露的
鯉魚轉移到清水中后,大部分有
一定中毒癥狀的魚體,都會逐漸恢復過來。
? as same as most other schizothoracinae fishes, qinghai - lake nakked car ps may be tetraploid that already were diploidization ; ? qinghai - lake nakked carps arose from some primitive barbinae fishes, which gradually became special population adapting to high altitude environment by involvement and natural selection, on protein electrophoresis, out of 20 protein loci among 132 individuals in the present experiment, only t mdh > amy est and pod showed polymorphism
在蛋白水平上,共檢測了132尾裸
鯉的20個遺傳座位,僅發現tf , mdh 、 amy 、 est和pod五個座位表現出多態性,其中, tf 、 mdh 、 amy和est四個座位均有
一對等位基因;而pod座位表現出復雜的電泳圖譜,未進行深入分析。
The stamp sheetlet issued today bears images from hong kong s traditional lunar new year s day parade, including the auspicious dragon and a golden carp, as well as other parade floats
今天發行的第四款小型張,載有香港傳統農歷大年初
一賀歲巡遊之情景,包括舞龍、模型
鯉魚及其他美輪美奐的花車。
Compared with the control, the effect of pyrethroid on haematological biochemical indices of carp was significant. the hb concerntration, rbc numbers, tp and ap numbers and the serum sodium level dropped ? the serum alt and ast activity and serum potassium level raised. these haematological difference of the treated groups were significant ( p > 0. 05 ) or very significant ( p > 0. 01 ) compared with the control group
與對照組比較,低濃度擬除蟲菊酯對
鯉魚的體長影響不顯著,對體重、攝食和行為有
一定的影響,其影響程度隨處理劑量的遞增和時間的延長而加強;在試驗後期較高濃度組部分
鯉魚發生間歇性中毒癥狀,繼而死亡。
Now suppose that next day, one of these eels, or pike, or carp, poisoned at the fourth remove, is served up at your table
誰都知道,那些梭子魚鰻魚和
鯉魚吃東西時是很貪婪的,它們把那隻兀鷹大嚼了
一頓。
Well, then, your guest will be poisoned at the fifth remove, and die, at the end of eight or ten days, of pains in the intestines, sickness, or abscess of the pylorus. the doctors open the body and say with an air of profound learning, the subject his died of a tumor on the liver, or of typhoid fever
於是這些梭子魚鰻魚和
鯉魚便是第四輪中毒,哦,假若第二天其中的
一條上了您的餐桌,那麼,您的客人就會第五輪中毒,在八至十天以後,他就會因腸胃疼痛或幽門潰爛而死。
